这里我要介绍的是如何使用VS2005中的ReportViewer控件动态显示需要绑定的报表（*.rdlc）。由于我们已经很习惯使用DataSet作为数据源去绑定类似于GridView或者DataGrid等控件，那么是否有方法将DataSet作为数据源就像绑定GridView这样去绑定报表呢？答案肯定的。
让我们先看下最简单的连接方法：Reporting Service使用dataset.xsd作为数据源，建立一个页面page.aspx对应一个reportviewer控件对应一张report.rdlc报表对应一个dataset.xsd数据源。运用这种模式，那么在VS2005中提供了一个强大的向导，只需按照向导操作，网上资料或者MSDN中都介绍的很详细如何使用这个向导，在此不再详细描述。
其次，也是我主要要介绍的，动态绑定到ado.net dataset：由于大部分数据都是采用ado.net dataset作为数据源绑定，如果使用提供的向导操作便不能进行动态绑定，对于后台操作非常不便，故不能使用向导操作。现在要设法动态绑定ado.net dataset到指定的report。
优点在于代码简单，操作灵活；
缺点在于设计report文件将变得非常令人头疼。
report文件是xml格式的，如果不使用向导那么就必须人为的去写这个xml文件（我研究了很久，没找到其他设计报表的方法，这麽写也是摸索出来的，掌握了就很方便了），特别当存储过程是动态的时候，设计这个报表的数据源将变得更为烦锁。但是同样的优点在于一切的问题只要掌握了如何去写这个文件，那么就等于解决了所有问题，独立性强。
二、使用WebForms ReportViewer控件
在一个WEB应用程序中，为了浏览在服务器上(report server)配置好的报表或者在本地文件系统（local file system）上的报表，你可以使用WebForms ReportViewer控件。
增加一个ReportViewer控件到一个Web应用程序
1、 增加一个新的Microsoft ASP.NET Web Site使用Microsoft Visual C# 或者 Microsoft Visual Basic。
2、 从工具箱中将ReportViewer控件拖到设计页面上，命名为reportViewer，当增加完之后，ReportViewer任务标签中会出现提示让你选择一个报表，此处可不去管它。
3、使用远程处理模式（Remote Processing Mode）浏览报表
下面的例子详细展示了如何提交一个报表存在于报表服务器上，这个例子使用Sales Order Detail Report。这张表报存在于SQL2005的示例（AdventureWorks）中，你只需安装SQL2005的示例，便能从里面找到，更详细信息关于示例，请看AdventureWorks Report Samples。
这个例子使用Windows综合认证，所以你必须首先在web.config中加入
C#
1protected void Page_Init(object sender, EventArgs e)
2{
3 if (!Page.IsPostBack)
4 {
5 // Set the processing mode for the ReportViewer to Remote
6 reportViewer.ProcessingMode = ProcessingMode.Remote;
7
8 ServerReport serverReport = reportViewer.ServerReport;
9
10 // Set the report server URL and report path
11 serverReport.ReportServerUrl =
12 new Uri("http://localhost/reportserver");
13 serverReport.ReportPath =
14 "/AdventureWorks Sample Reports/Sales Order Detail";
15
16 // Create the sales order number report parameter
17 ReportParameter salesOrderNumber = new ReportParameter();
18 salesOrderNumber.Name = "SalesOrderNumber";
19 salesOrderNumber.Values.Add("SO43661");
20
21 // Set the report parameters for the report
22 reportViewer.ServerReport.SetParameters(
23 new ReportParameter[] { salesOrderNumber });
24 }
25}
VB
1Imports Microsoft.Reporting.WebForms
2
3Partial Class _DefaultClass _Default
4 Inherits System.Web.UI.Page
5
6 Protected Sub Page_Init()Sub Page_Init(ByVal sender As Object, _
7 ByVal e As System.EventArgs) Handles Me.Init
8
9 If Not Page.IsPostBack Then
10
11 'Set the processing mode for the ReportViewer to Remote
12 reportViewer.ProcessingMode = ProcessingMode.Remote
13
14 Dim serverReport As ServerReport
15 serverReport = reportViewer.ServerReport
16
17 'Set the report server URL and report path
18 serverReport.ReportServerUrl = _
19 New Uri("http://localhost/reportserver")
20 serverReport.ReportPath = _
21 "/AdventureWorks Sample Reports/Sales Order Detail"
22
23 'Create the sales order number report parameter
24 Dim salesOrderNumber As New ReportParameter()
25 salesOrderNumber.Name = "SalesOrderNumber"
26 salesOrderNumber.Values.Add("SO43661")
27
28 'Set the report parameters for the report
29 Dim parameters() As ReportParameter = {salesOrderNumber}
30 serverReport.SetParameters(parameters)
31
32 End If
33
34 End Sub
35
36End Class
4、使用本地处理模式(Local Processing Mode)浏览报表
这个例子同样使用了AdventureWorks Report Samples，你可以在本文章的最下面点击下载我做好的例子。
（1） 打开一个Web Site提供报表的增加
（2） 从菜单栏选择增加现有项
（3） 将C:\Program Files\Microsoft SQL Server\90\Samples\Reporting Services\Report Samples\AdventureWorks Sample Reports\ Sales Order Detail.rdl 报表文件加入项目
（4） 重命名Sales Order Detail.rdl为Sales Order Detail.rdlc
（5） 下面的例子将会在本地模式下建立一个dataset作为报表的数据源显示报表
C#
1protected void Page_Init(object sender, EventArgs e)
2{
3 if (!Page.IsPostBack)
4 {
5 // Set the processing mode for the ReportViewer to Local
6 reportViewer.ProcessingMode = ProcessingMode.Local;
7
8 LocalReport localReport = reportViewer.LocalReport;
9
10 localReport.ReportPath = "Sales Order Detail.rdlc";
11
12 DataSet dataset = new DataSet("Sales Order Detail");
13
14 string salesOrderNumber = "SO43661";
15
16 GetSalesOrderData(salesOrderNumber, ref dataset);
17
18 ReportDataSource dsSalesOrder = new ReportDataSource();
19 dsSalesOrder.Name = "SalesOrder";
20 dsSalesOrder.Value = dataset.Tables["SalesOrder"];
21
22 localReport.DataSources.Add(dsSalesOrder);
23
24 GetSalesOrderDetailData(salesOrderNumber, ref dataset);
25
26 ReportDataSource dsSalesOrderDetail = new ReportDataSource();
27 dsSalesOrderDetail.Name = "SalesOrderDetail";
28 dsSalesOrderDetail.Value = dataset.Tables["SalesOrderDetail"];
29
30 localReport.DataSources.Add(dsSalesOrderDetail);
31
32 // Create the sales order number report parameter
33 ReportParameter rpSalesOrderNumber = new ReportParameter();
34 rpSalesOrderNumber.Name = "SalesOrderNumber";
35 rpSalesOrderNumber.Values.Add("SO43661");
36
37 // Set the report parameters for the report
38 localReport.SetParameters(
39 new ReportParameter[] { rpSalesOrderNumber });
40 }
41}
42
43private void GetSalesOrderData(string salesOrderNumber,
44 ref DataSet dsSalesOrder)

三、设计报表连接数据源
当做完以上工作后，还需要设计报表的连接数据源，用记事本打开Sales Order Detail.rdlc。你只需详细关注里面的DataSources和DataSets就可

其中DataSet 的
Dim dsSalesOrderDetail As New ReportDataSource()
dsSalesOrderDetail.Name = "SalesOrderDetail"//对应该属性
dsSalesOrderDetail.Value =dataset.Tables("SalesOrderDetail")//绑定已经存在的dataset
localReport.DataSources.Add(dsSalesOrderDetail)
只要rdlc文件符合规范，其中的Fields设置为所有得出列名，定义的datasource name没有规定，但是必须统一，既可。你只要按照这样的格式去写一个报表文件，那么任何dataset都是可以绑定上去的，也就是说比如从将一个存储过程返回的dataset绑定到一张报表上面。
提示：
所有的列名申明将是一个非常令人头疼的问题，我所能作到的最简单的方法是按照向导作出一张报表，然后提取里面的所有fields复制到我要产生的报表中，如果你有更好的方法还请尽快告诉我，谢谢。
最后就是在报表上增加你想要显示的数据了，增加Reports Item，绑定参数等等，在此不作为本文介绍的内容。
四、总结
对于动态绑定报表的优点实在是太多了，你可以像绑定一个DataGrid那样去绑定一张报表，而且Reporting Services支持强大导出的功能也会让你的报表更满足你的需要。你可以从不同的页面传递不同的参数到同一个报表显示页面，根据参数的不同显示不同的报表，后台的代码是非常简单，唯一比较繁琐的任务都在于报表本身的设计。
呵呵，总算写完了，如果你有更好的方法还请一定联系我，大家交流，共同进步。
